MOMBUR 1,?43562 TRANSFER DEVICE FOR REGISTERING APPARATUS Filed March 28, 1927 2 Sheets-Sheet 2 Patented Jan. 14, 1930 GEORGES MOMBUR, F, VERSAILLES, FRANCE TRANSFER DEVICE FOR REGISTERING APPARATUS Application filed March 28, 1927. Serial No. 178,947,

My invention relates to a transfer device for registering apparatus which may comprise a series of numbered disks disposed in axial alignment and so arranged that they '5 severally present along a reference line a series of numbers, the disks running from right to left indicating the numbers of units, tens, hundreds, etc., in the usual manner.

The object of m invention is to provide a transfer device or registering apparatus which is more compact and permits a closer spacing of index numbers of a given size than the usual devices of this nature.

The invention further aims to provide transfer mechanism which, while insuring a positive and accurate advance of the several register disks and an equally positive locking of such disks when they are not required to be in motion, is simple and rugged in construction. The accurate movements imparted to the registering disks by the transfer mechanism according to the present invention insure the alignment of the several index num here so that the result of the integration of the register can be easily read and without possibility of confusion.

The apparatus according to the present invention is characterized by a novel connecting system between successive registering disks, said system comprising a star wheel of special design, a portion of which lies between the adjacent disks, This wheel is so formed as to perform a triple function in cooperation with a driving pin which is carried by the driving disk, driven pins which are carried by the driven disk and a mutilated locking ring which is preferably formed integrally with the driving disk. It will be understood that the term driving and driven may be appropriately applied when considering any pair of adjacent'disks, although the driving disk of such pair will, in fact, be the driven disk with respect to a wheel disposed to the right of the latter. A particular advantage of this construction is that the separation between adjacent disks need be no greater than the thickness of the special star wheel or intermediate wheel, as it may be termed, disposed between adjacent disks, and

inasmuch as no appreciable force is required and in France March 29, 1926.

to advance the counting or register disks, this intermediate wheel may be made quite thin. The disposition of the several parts of the transfer mechanism is such that the drivin and driven engagements and also the locking engagement of the parts cooperating with the intermediate wheel, all occur in the plane of such Wheel, and this permits of an extremely compact arrangement of the entire registering mechanism.

Further objects and advantages of my invention will be apparent in the following detailed description wherein reference is had to the accompanying drawings, in which Figure 1 is a front elevation of a register device employing the transfer mechanism according to the present invention.

Fig. 2 is an elevation of a disk seen in the direction of the arrow A, Fig. 1 (driving side) in its inactive and locked position.

Fig. 3 is a view of the opposite side of the same disk seen in the direction of the arrow B (Fig. 1) (driven side) in one of its working positions.

Fig. 4: is a diametrical vertical section in the direction of the arrow C, Fig. 2, or as viewed from the rear in Fig. 1.

As will be seen in Fig. 1, the register may comprise for example, five counting disks, the first disk 1 of which carries a circular row so of driving ratchet teeth 2 or the like. The first disk may be made integral with the axle 3 and drive it directly. The opposite face of the first disk, that is its driving face, is identical with the driving face of any one of the other disks and is similar to the face shown in Fig. 2. It will be seen in this figure that the driving face of each disk is provided with a mutilated locking ring or flange 5 having an opening 6 of predetermined width. A catch or driving pin 7 projecting from a shoulder 7* concentric to the rim 5 being provided opposite said opening. a

In its circular course the catch or driving pin 7 may engage in one of the radial notches 8 formed in the teeth 8 of an intermediate star wheel 9 of special form mounted between two adjacent disks. If the notches were omitted the wheel 9 would present normally the shape of a pinion having four teeth for instance, as shown by the dash and dot line 4 (Fig. 2), and suitably designed to cooperate with pins 10- of the adjacent driven disk, said pms having preferably a cylindrical shape. This ad acent disk is provided on its driven face with ten of such pins as will be seen in Fig. 3, where 1t le desired to give indications based on the d ec1mal system. It will be understood that with the exception of the right hand disk 1, the remaining counting disks are freely rotatable about the shaft 3. The intermediate star wheels 9 are freely rotatable .about the stationary shaft 11 and function independently of one another. Each disk drives the ad acent disks of next higher order through one of the intermediate wheels 9 lying between adjacent disks. It will be apparent that the first or units disk (to the right in Fig. -1) may be driven in any suitable manner.

he form and relative disposition of the several parts hereinbefore described is such that when a driven disk is at rest in an indicatin position a driven pin 10 will be engage in a tooth gap 9 of the intermediate wheel 9, and said wheel will be locked against rotation because the sides of the two adjacent teeth between which such gap exists bear upon the surface of the locking ring 5 of the driving disk. It will be apparent when the parts are in-the positionshown in Fig.

2, that owing to the penetration of the cir cumferences of the said locking ring 5 and of the star wheel 9, the rotation of the latter is prevented, and since the toothed gap 9 of the said wheel closely engages the pin 10 ofthe driven disk (Fig. 3) at such time, the rotation of such disk will be prevented and its correct angular setting positively determined.

The wheel 9 will be operated once at each revolution of the driving disk by means of the catch or driving pin 7, the engagement of the latter in notch 8 of the intermediate wheel corresponding in angular movement to the coming of the cutaway part or opening 6 in locking ring 5 opposite a tooth 8 of the said wheel, thus allowing the rotation of the wheel to take place under the action of said driving pin.

The shape and dimensions of the intermediate star wheel 9 are determined in such a manner that, by reason of the action of the driving pin 7 of a driving disk, said wheel Will'be turned through an angle of 90 degrees at each actuation, this movement of the wheel causing the driven disk to be advanced onetenth of a revolutionflso as to bring the succeeding numeral to the index line, the parts being then locked againstdisplacement, as above set forth.

In this particular embodiment of my invention, the four quadrants of the intermediate star wheel are identical in form so that the operation above set forth will occur nuance i four times during each complete revolution of such wheel.

It will be apparent that tlie star wheel 9 with respect to the'pins 10 driven thereby constitutes a pinion, the said ins acting as the teeth of a' gear meshing with the teeth 4 gFigfl 2) ofsuch pinion (wheel 9) and drivmg pin 7 of the adjacent disk also acts as the tooth of a driving gear in advancing the said star wheel. Considered as gears and pinions, the driving ratio between the driving disk and intermediate wheel 9 is higher than the ratio between said wheel and the disk driven thereby because the radius of driving pin 7 is greater than the radius of driving pins 10 with respect to the axis of the disks. This results in a somewhat gearedup drive which has the advanta e of bringing about a more rapid shift 0 the driven disk from one indicating position to another than if it were acted upon directly by the driving disk. This is desirable because it reduces the period during which it is diflicult to read the index due to the movement of one or more of the disks.

It will be apparent that the use of an intermediate wheel which is actuated and in turn communicates its action in one and the same plane, allows of reducing to the utmost degree the thickness of said wheel and the necessary resulting separation between two disks. Conseguently the numbers of the indicating ap a-ratus according to the present invent-ion W111 be very close together and because of the accuracy of the disk locking means hereinbefore set forth, perfectly in line, so that the registered number may be very easily read.

It will be understood that I do not limit my invention to the particular mode of execution hereinbefore specifically described and shown in the annexed drawing inasmuch as many modifications may be made in the construction .without departing from the spirit of my invention, such for example as modifications concerning the number of teeth of the intermediate wheel 9 or such changes as would be required to adapt the device to a difierent numerical system.
